I thought the service to Toh Tuck Rd End should be UBC 205?
UBC 205 operates from Block 61 along Corporation Drive to
Shipyard Rd (Jurong Shipyard) after the 1971 re-organisation.
Corporation Dr, Block 61, along Corporation Dr, Corporation Rd,
Jln Ahmad Ibrahim, Jurong Pier Rd, Jln Buroh, Tanjong Kling Rd, 'U'
turn in front of National Iron & Steel Mills Ltd., Tanjong
Kling Rd, Shipyard Rd, Jln Samulun, Shipyard Rd (near Mobil
Refinery Co).
It was replaced by SBS 249 during the rationalisation of Jurong
Town Bus Services in 1978.
Then 10 years later, on 11th July 1988, here comes the second
SBS 205.
Clementi Int, (Clementi Ave 3), Commonwealth Ave West, Toh Tuck
Rd, Jln Jurong Kechil, Jln Anak Bt, Upp Bt Timah Rd, Jln Jurong
Kechil, Toh Tuck Rd, Commonwealth Ave West, (Clementi Ave 3),
Clementi Int.
This service was merged with 173 somewhere in 1992.
